, SUCTION CARPET-SWEEPER.

Application filed September 18, 1916. Serial No. 120,594.RE1IS To allwhom it may concern:

Be it known that I, JOHN VANuER PUTTEN, a citizen of the United States,residing at New Philadelphia, in the county of Tu'scarawas and State ofOhio, have invented a new and useful Suction Carpet- Sweeper, of whichthe following is a specification.

This invention relates to improvements in devices for brushing andpneumatically cleaning floors and floor coverings such as carpets, rugsand the like and comprises a device provided with a plurality ofcompartments adapted to be located 1n uxtaposition to the surfaceto becleaned, one of said compartments being unobstructed and so shaped thata strong inrush of a r 1I1t0 the device takes place through saidcompartment, the remaining compartments being provided with rotatablebrushes for removing fine dirt and dust.

The object of the presentinvention is to generally improve portablesuction sweepers and to combine in a device of the character mentioned amotor driven suction creating device so constructed as to produce anextremely strong inrush of air through the central portion of the devicewith a mechanically operated brushing device preferably operated bycontact with the surface to be cleaned.

A further object is to provide a sweeper of the character mentionedcomprising a series of rectangular compartments arranged to be locatedadjacent the surface to be cleaned these compartments being formed bypartitions of less height than the casing thus forming communicationbetween all of the compartments and the suction creating device thecentral compartment being unobstructed, leaving a passage directlythrough the casing to the suction creating device, the end compartmentbeing provided with brushing devices, thus allowing for the inrushof'air through the central compartment to pull the air from each of theside compartments.

A still further object is to provide a sweeper of this character with aseries of compartments arranged to be located adjacent the surface to becleaned, the central compartment being unobstructed and having the lowerportion of the front wall removed in order to create an unusually stronginrush of air through said compartment to Specification oi LettersPatent.

the suction creating device, thus permitting the central compartment ofthe machine to pick up large particles of rags, paper, string and thelike while the end compartments are provided with brushing devicesadapted to remove threads, lint and finer particles of dust and dirtcommunication being provided at the upper portions of theend and centralcompartments, allowing the air to be pulled from the side compartments.

A further object is to provide a machine of the character referred towith an opening in the casing for receiving the usual flexible hose towhich attachments are connected for cleaning draperies, upholstering andthe like, a sliding plate being provided for normally covering saidopening, said plate serving also as a name plate, thus giving the devicea finished and pleasing appearance.

A further object is to provide a sweeper of the character referred to inwhich the lower portion of the sweeper casing, which comes into contactwith the floor covering is composed of a non-discoldring or noncolorablealloy.

In the drawings: Figure 1 is a perspective view of a sweeper constructedin accordance with my invention. Fig. 2'is a vertical transverse sectionthrough the same.- Fig. 3 is a fragmentary bottom plan view of thesweeper. Fig. 4: is a front elevation. Fig. 5 is a fragmentary interiorview of the front Wall, showing the means of attaching the name plate.Fig. dis a section on the line 6-6, Fig. 5. Fig. 7 is a perspective viewof the detachablelower portion of the casing, showing the brushes andwheels assembled therein. Fig. 8 is a similar view showing the brushesand wheels removed.

Similar numerals of reference indicate corresponding parts throughoutthe several figures of the drawing.

In the present form of suction sweepers which are in actual use anelongated and relatively narrow slot is provided in the under wall ofthe casing and arranged to be held in contact with the surface to becleaned. With this construction of sweeper, although removing dust anddirt and smaller particles of such litter and rubbish ordinarilyaccumulates in a sewing room cannot be so readily removed with the usefiner particles of dirt, but which will easily and readilypick up largerpieces of rags,

paper and the like. The present machine is a self-contained, portabledevice, com-prising a casing having a suction creatlng device therein,the lower portion of the casing which contacts with the floor beingdivided into three rectangular compartments communicating with thesuction creating device,

the central compartment being unobstructed and having its front wallterminating at a considerable distance from the floor, the two endcompartments being provided with rotary brushes preferably operated bythe driving. wheels upon which the casing is mounted, an aperture beingformed in the forward face of the casing for the purpose of' attachingthe usual hose, which carries attachments, for cleaning upholstery,portieres, drapery and the like, a name plate being slidably mountedupon the casing for the purpose of normally covering said aperture, theentire lower portionof the casing which carries the three compartmentsabove referred to being preferably formed separate from the remainder ofthe casing and composed of a non-discoloring alloy.

Referring more especially to the construction illustrated in theaccompanying drawings, the numeral 1 indicates the "casing of thesweeper, the numeral 2 the fan casing which is preferably formedintegral therewith and the numeral 3 the electric motor, which may be ofany well known design and is mounted upon the fan casing by means ofscrews 4: or their equivalents. Within the fan casing 2 is a fan 5operatively connected to the motor 3, said motor and fan being adaptedto exhaust the air from the casingv '1 through theexhaust collar 5,which is preferably formed integral with the casing in the usual manner.To the exhaust collar 5 .is connected a dust receptacle 6 shown ing-"erator for the purpose of moving the sweeper over the floor or othersurface to be cleaned. The lower portion of the casing is preferablyformed separate from the body portion of the casing and comprises aframe 8 of oblong form having the compartments 9 at the ends thereof forthe purpose of receiving the drive wheels 10, said wheels being pivotedwithin said compartments as shown at 11. The frame 8 is provided withscrew threaded apertures'12 for the purpose of attaching the same to thebody portion 1 rename of the casing. Spaced partitions 13 divide theframe 8 intothree rectangular compartinents,. each of said compartmentsbeing preferably square. The partitions 13 and the end walls 14 are eachprovided with an enlarged or thickened portion 15 having screw threadedapertures 16 therein for the purpose of receiving screws 17 to attachthe bearings 18, the shafts 19 ofthe brushes 20 being journaled withinsaid bearings. Corrugated rollers 21 are provided upon the outerextremities of the shafts l9, driving belts 22 being located over saidrollers and in the grooves 23 of the drive wheels 10, thus causing thebrushes 20 to be rotated with the movement of the machine.

It will be noted that the brushes 20 are located wholly within the endcompartments 24. while the central compartment 25 is unobstructed,leaving a direct passage for the inrush of air through the cut awayportion 26 in the'front wall of said compartment,

through the compartment25 and casing l to the fan.

As it is usual to provide, with sweepers of this construction, a hoseadapted to be detachably' secured to the casing, said hose beingprovided with attachments or nozzles for cleaning upholstery, portieresand similar articles, an aperture 27 is provided in the front wall ofthe casing 1 for the purpose of attaching said hose. The aperture 27 isadapted to be normally closed by the sliding plate 28, said plate havinga disk portion. 29 arranged to be located over the aperture. A. disk 30is located against the inner face of the outer wall of the casing, saiddisk being connected to the plate 28 by means of suitable screws or pins31, which are located through the horizontally disposed slot 32, formedat the front wall thus slidably mounting the plate 28 upon the frontwall of the casing. A plate 33 is fixedly. mounted'upon the front faceof the casing, adjacent the aperture 29 and is proi vided with theconcaved end 34 adapted to receive the disk portion 29 of the slidingplate 28. The sliding plate 28 not only serves as a cover plate for theaperture 29 when the attachments are not in use, but in combination withthe plate 33 forms a, name plate upon which the name of the machine andpatent numbers or other information regarding the machine may be placed.

From the above description it will be seen that my sweeper comprises acasing having a motor operated'fan, located therein a plurality ofrectangular compartments formed in the lower portion of said casing, allof said compartments communicating at their upper ends with the fancasing, brushes mounted in the end compartments and adapted to berotated by the movement of the sweeper upon the surface to be cleaned,the central compartment being unobstructed and having the lower portionof its front wall cut away, allowing for an extremely strong inrush ofair through said compartment to the suction creating device, wherebylarge pieces of cloth, paper, string and the like may be taken upthrough said central compartment, while part of the lower edge of thecasing is adapted to be substantially in contact with the surface to becleaned, the rotating brushes therein disturbing the dust and fine dirtupon the surface'over which the sweeper is moved, the strong current ofthe air passing through the central compartment pulling the air from theend.

compartments, thustaking up the fine dirt and dust which is disturbed bythe rotary brushes. The sweeper is also provided with the aperture forattaching the hose for special cleaning attachments and nozzles, acombined name plate and cover plate for said aperture being slidablymounted upon the sweeper casing, thus giving the device a finished andpleasing appearance.

Although the drawings and above specification disclose the best mode inwhich I have contemplated embodying my invention I desire to be notlimited to the details of such disclosure, for, in'the further practicalapplication of my invention, many changes in form and construction maybe made, as

circumstances require or experience suggests,

without departing from the spirit of the invention, within the scope ofthe appended claims.
